only thing i can add on to Bluer's info is that your stays are based on a 12 month set up.
each january you start over again to get credits and keep you at the youfirst level.
if you have 2 visits in one year and skip a year, you don't necessarily keep your level status of blue, gold, platinum
Its a rolling 12 month not January.
From the website.
Qualification for Membership Levels will be determined based on a rolling 12-month cycle, beginning July 15th, 2008 (the YouFirst Program Launch Date). Meaning, a Member must stay at a Loews property 2 times within any 12-month period following 7/15/08 to earn Blue status, 5 times within any 12-month period following 7/15/08 to earn Gold status, and 10 times within any 12-month period following 7/15/08 to earn Platinum status.
If a Member does not earn enough qualifying stays during the 12 months following a change in status to progress to the next level of membership or to maintain the Member’s existing level of membership, the Member will be downgraded to the next-lower level of membership on the 1-year anniversary of that change in status (12 months after earning status). For example, if a Member earns Gold status on October 1, 2008, but does not qualify for Gold status as of September 30, 2009 (has not had at least 5 qualifying stays in the most recent 12 months), that Member would be downgraded to Blue status as of October 1, 2009.
Benefits will also be provided on a rolling 12-month schedule. Per the example above, the Member would begin enjoying Gold benefits as soon as he earned Gold status on October 1, 2008 and would continue to enjoy those benefits for the following 12 months, until September 30, 2009. If, at that time, he has not had at least 5 qualifying stays in the most recent 12 months, the Member would be downgraded to Blue status and begin enjoying Blue-level benefits for the following 12 months.
So if you stay say 5 times in the next year you will become gold. From the day you get your gold status you need to stay atleast 5 more times in the next 12 months to keep that gold status. If you don't then you are downgraded to the next level. It's always based on 12 months from receiving a new status.
